Overview
R5F10NMJDFB#30 from Renesas is an RL78/I1C 80-pin ultra-low-power 16-bit MCU with 256 KB flash, 16 KB RAM, hardware AES-128/192/256, independent power supply RTC, and 24-bit ΔΣ A/D converter - designed specifically for electric AMI power meter applications requiring secure metering, long battery life, and high-precision energy measurement.
For engineers reviewing the R5F10NMJDFB#30 datasheet, R5F10NMJDFB#30 pinout, R5F10NMJDFB#30 application, or R5F10NMJDFB#30 equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-chain-ready availability details - all grounded in Renesas' official R01DS0281EJ0231 Rev.2.31 documentation.
Technical Context
The R5F10NMJDFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable clock sources including 32 MHz PLL, 24 MHz high-speed on-chip oscillator (±1.0% accuracy), and 15 kHz low-speed oscillator. It supports HALT, STOP, and SNOOZE low-power modes with VDD operating range of 1.9–5.5 V and industrial temperature range (−40°C to +85°C).
It integrates a dedicated 24-bit ΔΣ A/D converter (3 channels), 8-channel 16-bit timer array, event link controller (ELC) for peripheral signal chaining, data transfer controller (DTC), and LCD controller supporting up to 34 segments and 8 commons - all coordinated under a single power domain with independent VRTC and battery backup capability.
